3. Litigation

On March 20, 2009, at the conclusion of a trial in Illinois State Court, Twelfth Judicial Circuit, Circuit Court of Will County, a jury entered a verdict of $23.75 million against us, a federally authorized motor carrier with which we contracted, and the motor carrier’s driver. The award was entered in favor of three named plaintiffs following a consolidated trial, stemming from an accident that occurred on April 1, 2004. The motor carrier and the driver both admitted that at the time of the accident the driver was acting as an agent for the motor carrier, and that the load was being transported according to the terms of our contract with the motor carrier. Our contract clearly defined the motor carrier as an independent contractor. The verdict has the effect of holding us vicariously liable for the damages caused by the admitted negligence of the motor carrier and its driver. There were no claims that our selection or retention of the motor carrier was negligent.

Given our prior experience with claims of this nature, we believe the court erred in allowing these claims to be considered by a jury. As a result, we sought relief from the verdict in the Appellate Court of Illinois, Third Judicial District. On March 30, 2011 the Illinois Court of Appeals issued an opinion affirming the verdict. Although we and our insurance carriers will continue to pursue legal recourse, we determined that it was appropriate to record a $5.9 million charge in the first quarter of 2011. This amount represents our $5.0 million insurance deductible plus accrued post-judgment interest on that amount. Our insurance carrier is responsible for the remaining verdict amount and related post-judgment interest.

We are not subject to any other pending or threatened litigation other than routine litigation arising in the ordinary course of our business operations, none of which is currently expected to have a material adverse effect on our financial condition, results of operations, or cash flows.

Fair Value Measurement
Fair Value Measurement

4. Fair Value Measurement

Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

 

   

Level 1 - Quoted market prices in active markets for identical assets or liabilities.

 

   

Level 2 - Observable market-based inputs or unobservable inputs that are corroborated by market data.

 

   

Level 3 - Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets.

A financial asset or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.

 

The following tables present information as of March 31, 2011 and December 31, 2010, about our financial assets and liabilities that are measured at fair value on a recurring basis, according to the valuation techniques we used to determine their fair values.

The estimated fair values of debt securities held as available-for-sale are based on other market data for comparable instruments and the transactions related in establishing the prices. In measuring the fair value of the contingent payment liability, we used an income approach that considers the expected future earnings of the acquired businesses and the resulting contingent payments, discounted at a risk-adjusted rate.

The table below sets forth a reconciliation of our beginning and ending Level 3 financial liability balance.

5. Stock Award Plans

Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense as it vests. A summary of our total compensation expense recognized in our statements of operations for stock-based compensation is as follows (in thousands):

March 31,
 
     2011      2010  

Stock-based compensation expense

   $ 12,510       $ 4,664   

 

Our 1997 Omnibus Stock Plan allows us to grant certain stock awards, including stock options at fair market value and restricted shares and units, to our key employees, directors, and other third parties. A maximum of 28,000,000 shares can be granted under this plan; approximately 7,090,661 shares were available for stock awards as of March 31, 2011, which cover stock options and restricted stock awards. Awards that expire or are cancelled without delivery of shares generally become available for issuance under the plans.

Stock Options—The contractual lives of all options as originally granted are ten years. Options vested over a five-year period from the date of grant, with none vesting the first year and one quarter vesting each year after that. Recipients are able to exercise options using a stock swap which results in a new, fully-vested restoration option with a grant price established based on the date of the swap and a remaining contractual life equal to the remaining life of the original option. Options issued to non-employee directors vest immediately. The fair value per option is established using the Black-Scholes option pricing model, with the resulting expense being recorded over the vesting period of the award. Other than restoration options, we have not issued any new stock options since 2003. As of March 31, 2011, there was no unrecognized compensation expense related to stock options since all outstanding options were fully vested.

Restricted Stock Awards—We have awarded performance-based restricted shares and restricted units to certain key employees and non-employee directors. These restricted shares and restricted units are subject to certain vesting requirements over a five-year period, based on the company’s earnings growth. The awards also contain restrictions on the awardees’ ability to sell or transfer vested shares or units for a specified period of time. The fair value of these shares is established based on the market price on the date of grant, discounted for post-vesting holding restrictions. The discounts have varied from 12 percent to 22 percent and are calculated using the Black-Scholes option pricing model. Changes in the measured stock price volatility and interest rates are the primary reason for changes in the discount. These grants are being expensed based on the terms of the awards.

We have also awarded restricted shares and units to certain key employees that vest primarily based on their continued employment. The value of these awards is established by the market price on the date of the grant and is being expensed over the vesting period of the award.

We have also issued to certain key employees and non-employee directors restricted shares and units which are fully vested upon issuance. These shares and units contain restrictions on the awardees’ ability to sell or transfer vested shares and units for a specified period of time. The fair value of these shares is established using the same method discussed above. These grants have been expensed during the year they were earned.

As of March 31, 2011, there was unrecognized compensation expense of $156.0 million related to previously granted restricted equity. The amount of future expense will be based primarily on company performance, future awards, and certain other conditions.

Employee Stock Purchase Plan—Our 1997 Employee Stock Purchase Plan allows our employees to contribute up to $10,000 of their annual cash compensation to purchase company stock. Purchase price is determined using the closing price on the last day of the quarter, discounted by 15 percent. Shares are vested immediately. The following table summarizes employee stock purchase plan activity for the period:

C.H. Robinson Worldwide, Inc. and its 80 percent (or more) owned U.S. subsidiaries file a consolidated federal income tax return.
